Make your way to the bottom of the pyramids by finding the difference between the
numbers on 2 blocks next to each. Put the answer into the number on the block below.

 between 40 and 10
 is 30

compensating.                               I did 4.6 – 1 = 3.6m. Then I did                I knew 1.87 + 0.13 makes 2.
I took away a tidy 2 from 4.6               3.6 – 0.8 = 2.8m. Then I did                   So then I added on another
which makes 2.6. Then I added               2.8 – 0.07 = 2.73m                             2.6 to make 4.6m. So the

Look at how the problem below can be represented as a multiplication sum by finding
a common factor for each addend.

                     56                  +                 16                      =            72

Rewrite these sums into multiplication problems by finding the common factor. The

I am learning to combine proportions and work out what parts the total is made up of.

Complete the table below to show for each stack of cubes.

           Stack                           Ratio                     Fraction                      Percentage
                                       (light:dark)              light      dark                light      dark

A

B

Now complete the table to show what would happen if you combined Stacks A and B.

          Stack                           Ratio                    Fraction                       Percentage
                                      (light:dark)             light      dark                 Light      dark
A + B (shade correctly)




Use the information about the following stacks of cubes to solve the problems below.

Stack A                      Stack B                       Stack C                           Stack D
2 light : 8 dark             13 light : 17 dark            9 light : 1 dark                  28 light : 12 dark

        Stacks                          Ratio                    Fraction                        Percentage
                                    (light:dark)             light      dark                  light      dark
